1/// Display mapping system for Editor/Input.
2///
3/// This module implements a layered display mapping architecture:
4/// - **WrapMap**: Handles soft-wrapping (buffer → wrap rows)
5/// - **FoldMap**: Handles folding (wrap rows → display rows)
6/// - **DisplayMap**: Public facade for Editor/Input
7///
8/// The goal is to provide a clean, unified API where Editor only needs to know
9/// about `BufferPoint ↔ DisplayPoint` mapping, without worrying about internal wrap/fold complexity.
